Another prominent exclusive arrangement with Apple for the iPhone is expected to conclude in a matter of months, when it is anticipated that Deutsche Telekom will lose sole access to the iPhone in Germany.

Google Android ousted Research in Motion's BlackBerry platform as the top-selling smartphone operating system in the U.S. for June quarter, while Apple's iPhone -- available in just two models and on one carrier -- took third.

The U.S. government on Monday announced new rules that make it officially legal for iPhone owners to "jailbreak" their device and run unauthorized third-party applications. In addition, it is now acceptable to unlock any cell phone for use on multiple carriers.

While its inevitable that Apple will introduce a version of its iPhone handset for U.S. wireless carriers outside of AT&T, it's T-Mobile that stands as the front-runner for the gig rather than Verizon, one investment research firm said Thursday.

A new report from the Federal Communications Commission did not describe the U.S. wireless industry as having "effective competition" for the first time in years, suggesting major carriers -- including AT&T, the exclusive provider of the iPhone -- could come under federal scrutiny.

After poring over court documents from 2008, Engadget has confirmed that Apple and AT&T originally agreed to a five-year exclusive arrangement for the iPhone. Whether that deal is still in place, however, is unknown.

Despite billions of dollars invested in its network in the last year, a new survey has found that AT&T customers report the most dropped calls of any U.S. carrier, and those users are also the least satisfied with their service. (Update: AT&T has responded to the survey findings, as noted below).

Palm this week parted ways with the ad agency that produced its widely panned advertising campaign for the Pre smartphone. And U.S. wireless carrier T-Mobile is offering up to $350 for iPhone trade-ins for new customers who switch to the HTC HD2.

With speculation of a CDMA iPhone compatible with Verizon's network renewed this week, one prominent analyst said he believes Apple's alleged negotiations could be more about competing with Android than anything else.

As bandwidth-heavy smartphones like Apple's iPhone turn huge profits for handset makers, wireless carriers across the world have struggled to keep up with bandwidth needs. One executive said this week that new business models must be explored for carriers to remain profitable.

(Mobile World Congress) Apple is not officially present at this week's Mobile World Conference in Barcelona, Spain, yet carriers are talking about the iPhone and rivals are introducing what they hope to pitch as "iPhone killers."

Apple has obtained the trademark for "i-phone" from a Chinese company that applied for ownership of the name in 2004, and a hands-on with Google's Nexus One phone concludes it isn't an "iPhone killer."
